摘要
通过耦合振动理论、模态分析和实验测量研究了二维振动方向变换器的耦合振动的谐振频率方程和特定输出端的位移振幅。实验结果表明,理论分析得出的纵向振动谐振频率与实验结果相符,且通过实验与模态分析可知,此二维振动方向变换器有很好的聚能作用。
The resonant frequency equation and the special output terminal displacement amplitude of the two dimensional vibration direction convertor are studied by coupled vibration theory, model analysis and experimental measurement. The results show that the measured frequency agrees with the calculated frequency. Moreover, the experimental and model analysises also show that the energy gathering function of the two dimensional vibration direction convertor is very good.
